    Tips: What is the Alarm Point of Toxic Gas Detector?

    1. Short-term exposure limit alarm
    Short-term exposure limit or STEL is a same physical quantity with the TWA (rather than a unit). The difference between STEL and TWA is that its time is shorter, 15 minutes in general, namely STEL is the time weighted of 15 minutes. The calculation method of STEL is determined by the sampling time. The value of STEL is defined as the weighted of 15 minutes, thus several times of averaging will be carried out within 15 minutes (the times shall not be less than 3). The final value shall be the value of STEL. So what’s the point? Workers who are exposed to this concentration for short periods (usually 15 minutes) are not subject to permanent or non-recoverable tissue damage or reduced body alertness.

    2. Time-weighted average alarm
    Time-weighted average or TWA refers to the time weighted average concentration of a chemical exposed in the air in a 8-hour working day and 40-hour working week, such a chemical will hardly have a harmful effect on the workers who come into contact with it every day under this restriction. The calculation method of TWA: fetch number at specific time within the 8 hours and then calculate the average value. Taking into account the effectiveness and practicability of the results, it requires that the time interval of sampling shall be less than 15 minutes. The average value of all the results shall be the TWA value of 8 hours.

    Dear Noah, thanks for your ordering and comment. To ensure the accuracy of the measurement, our gas detectors adopt the high-performance sensor so the cost is relatively higher. Good gas detector deserves this price.
